I made a port of my old ATMega8 HID Multimedia Dial project to the STM8.  It is now on github

The multimedia dial can control volume and mute.  When I double click the switch, it changes mode for media playback Next/Prev.

This version uses the STM8S003.  I have included a SWIM hardware debugger connector and soldered down the micro USB. (lost my bag of breakout PCB)

Also upgraded to a couple of RGB LED.

This project uses HID, so it is a good way for testing the changes I made to the STM8 VUSB. I have also recompiled USB2LCD with the new VUSB library and it seems to be working.
